To (ZZZ whom it may mam.

Be it known that We, Josnrrr l-l. HUM- PHREY and EDWARD 230m, citizens of the United States, and residents of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Time-Controlled SWitch-Gperating Devices, of which the following is specification, containing a full clear and' exact.

description, reference being had to the aceginpenying drawings, forming" a part here- 01.

' Our invention relates to certainnew and useful improvements in time controlled 1!! switch operating devices, which is so arranged that .it will operate the lighting switch-of an automobile at a predetermined time.

A further object is to construct a time controlled switch operating device for antomobiles Which can he set so that the lights will be automatically turned on at the hour designated by law.

In the drawings,

In the construction of our device We employ a clock 6. This clock is of ordinary construction and therefore will. not be described in detail. This clock is secured Within a housing 7, which is provided with a flange 8 by means of which the housing is secured to the instrument board 3- of an automobile. The housing '7 has the portion '10 projecting forward from the flange 8. This projecting portion is provided with bayonet grooves 11, which receive 12, these pins being secured to ing 13 of the clock, The cs r further held against rotation ofe set screw 14 which passes in. is

I. portion 10 and secures the cioci: egeinst jolting out of the beyonet joint. The clock isfproyidecl with the usual hands 15 end 26,, lo lIlCllCflilUlQ the hour hand. The cloelr cese13 is provided with a grooved flange 17, the grooved portion extending or fitting over the projecting portion 10 of the housing 7. The flange 17 is provided With projecting ears 18, which are. adapted to be bent over a ring 19 formed of insulating material. Secured to the ring 19 by means of screws 20 is a glass cover 21. The ring 19 is provided with an internal flange which is recessed to receive a conductor ring 23. This conductor ring has integrally formed contact brushes 24: and 25 which are spaced apart sufficiently .to allow the of two strips of conducting material and -1s secured to the housing 7 but fully insulated therefrom by means of the insulation 27 and insulating Washer 28. Secured to the brush 96 is a conductor 29. The opposite end of this conductor is secured to at binding post 30 mounted on the insulat ing plate 31. Secured to the binding post 30 is a onductor 32, which leads to the coil 33 oi an electro-inagnet. The coil of the electromagnet is connected to the coil 84 by means of a conductor while the coil 34 is connected to the battery 36 by means of the conductor 37. Secured to the hatte1y 36 is a conductor 38 which has. its free end attached to end grounded in a binding post 39, this binding post being in turn secured to the-housing 7. The

Henge 8 is provided with a downwardly proiecting portion. i0 through which ent'nd. the shank d1 a switch. This switch 1 an insulating bloc: 42, and

I; n T

not wneli me a.

of a conductor 49, the conductor 47 leading to the lamp 50. From this lamp :1 return conductor 51 leads to the batterv.

()ur object in interposing the switch 48 in the lamp circuit is for the reason that the hour hand will pass the contact brushes 34 and 35 twice in twentvtour hours, and it is to obviate the possibility of the lights being turned on when not wanted or while the machine is in the garage that this switch is installed. The Shani: 41 projects through th switch housing 42 (see Fig. 4-,) and is the purpose of pernitting' the rod to contact therewith. The rod 52 is support ed by means the bra let The arma' ture 5 1? of the electroona net extends downward and is provided with an opening which passes over the bar rod (2. This bar has mounted thereon washers 56 which are placed. on either side of the armature and are retained in position by means of pins 57, so that. when the armature is ope ated in either direction, it will come in contact with one of the 'uisliers 56 and move the bar 552 forward or backward.

The operation ot' our device is as follows:

After the proper connections have been made the device is set, for lighting. For instance, the law requires the ')l0})cl iights to he turned on at five ocloclz. The insu lating ring 19 is adjusted so that the contact brushes and will assume the po sition shown in Fig. 1, that is, directly opposite the numeral live on the clock. The switch 4-8 i" then turned on... Then as the clock runs, the hand 15 will contact with the brushes 24 and This will complete the circuit through the electro-inagncts by means of the conductors and leading from the battery, the conductor leading from the brushes 26 and the conductor ring 23, the return circuit being made through the housing 7. the casing 13 being in direct conirzua'; with this housing-the electric circuit necessarily passes through the works of the clock and through the hand 15, so that a complete circuit is established. This energizes the coils 33 and 34 of the electro-magne't pulling the armature 54 forward. This in turn imparts movement to the. rod 52 which contacts with the end of the shank 41, and operates the light switch. Vi e may if desired leave the light circuit intact, that is, operate it by means of the shank 41 only, and place the switch in the clectr0-magnet circuit without dcparting from the spirit of our invention.

the use of our device any clock furnishcd with an automobile can be utilized, the only change necessary being to install the housing 7 with its several parts and to mount the or crystal 28 on the time setting portion or insulating ring 19. Thus it will be seen that the device is coinparatively cheap in construction and does not necessitate a great deal of reconstruction for installin the same in an automobile.

Having fully described our invention, what we claim is:

l. A. time controlled switch operating de vice con'iprising a housing, a ring of insulating material rot-stably carried thereby, a conductor contact brushes secured to said insulated ring, a clock located in said housing and adapted to have one of its hands contact; who said brushes, an clectro-magnet adapted. to be energized when said contact is made, and a switch adapted to be closed by said i'i'ia g net when the sanie is energized.

A time controlled switch operating device coniprising a housing, a ring of insulating: material rotatably carried thereby, a conductor ring having integrally formed contact. brushes secured to said insulating ring. a clock located in said housing and adaptcdto have one; of its hands contact with said brushes, :1 Contact brush carried by and insulated from said housing, said brush contacting with the conductor ring, an electro-nnignet, a connection between the clecti'o-inagnet and last mentioned contact brush, electric conductors secured to the contact brush and electric-magnet whereby the same is energized when contact is made bet ween the hand and the brushes carried by the insulating ring, and a switch adapted to be closed by said electro-rnagnct when the same is energized, and manually operated to open the same.

In testimony whereof, we have signed oud names to this specification.
